Hi,
Take a look in our [ardusub documentation here](https://www.ardusub.com/hardware/components.html), that will describe and explain each component.

I think its logical to keep the costs down. Otherwise you would need another way to get your serial data and video feed to the top side. Ethernet is a good and cheap way and I haven’t found a device that can do this for less money than a raspberry pi paired with a phantom X.
